Hariho ibyiciro 4 byingenzi byo gukosora iyerekwa - emmetropiya, myopiya, hyperopiya, na astigmatism.
Emmetropiya ni iyerekwa ryiza.Ijisho rimaze gukuramo urumuri kuri retina kandi ntirisaba gukosora ibirahure.
Myopia izwi cyane nko kureba-hafi.Bibaho iyo ijisho ari rito cyane, bikavamo urumuri rwibanda imbere ya retina.
Kugirango ukosore myopiya, umuganga wamaso yawe azaguha gukuramo lens (-X.XX).Izi lens zo gukuramo zisunika ingingo yibanze inyuma kugirango ihuze neza kuri retina.
Myopia nuburyo bukunze kwibeshya bwo kugabanuka muri societe yubu.Mubyukuri, mubyukuri bikekwa ko ari icyorezo cyisi yose, kuko buri mwaka abaturage benshi basuzumwa niki kibazo.
Aba bantu barashobora kubona hafi cyane, ariko ibintu biri kure bisa nkibidasobanutse.
Mu bana, urashobora kubona umwana afite ikibazo cyo gusoma ikibaho kwishuri, afite ibikoresho byo gusoma (terefone ngendanwa, ibitabo, iPad, nibindi) bidasanzwe mumaso yabo, yicaye hafi ya TV kuko "badashobora. reba ”, cyangwa ndetse no kwikinisha cyangwa kubakubita amaso cyane.
Ku rundi ruhande, Hyperopia, ibaho iyo umuntu ashobora kubona kure cyane, ariko ashobora kugira ikibazo cyo kubona ibintu hafi.
Bimwe mubibazo bikunze kugaragara hamwe na hyperopes mubyukuri ntabwo aruko badashobora kubona, ahubwo ni uko barwara umutwe nyuma yo gusoma cyangwa gukora akazi ka mudasobwa, cyangwa ko amaso yabo akunda kumva ananiwe cyangwa ananiwe.
Hyperopia ibaho iyo ijisho ari rito cyane.Kubwibyo, urumuri rwibanze gato inyuma ya retina.
Hamwe niyerekwa risanzwe, ishusho yibanze cyane hejuru ya retina.Kurebera kure (hyperopiya), cornea yawe ntisubiza urumuri neza, bityo ingingo yibanze igwa inyuma ya retina.Ibi bituma ibintu byegeranye bisa nkaho bidasobanutse.
Kugira ngo ukosore hyperopiya, abaganga b'amaso bandika hongeweho (+ X.XX) lens kugirango bazane ingingo yibanze imbere yubutaka neza kuri retina.
Astigmatism nizindi ngingo zose.Astigmatism ibaho mugihe imbere yijisho (cornea) itazengurutse neza.
Tekereza kuri cornea isanzwe isa na basketball yaciwemo kabiri.Nibyiza byuzuye kandi bingana mubyerekezo byose.
Cornea ya astigmatique isa cyane namagi yatetse yaciwemo kabiri.Meridian imwe ni ndende kuruta iyindi.
Kugira meridiya ebyiri zitandukanye zijisho ryibisubizo bivamo ingingo ebyiri zitandukanye zo kwibandaho.Kubwibyo, ibirahuri bigomba gukorwa kugirango bikosorwe byombi.Iyi nyandiko izaba ifite imibare ibiri.Kurugero-1.00 -0.50 X 180.
Umubare wambere werekana imbaraga zikenewe mugukosora meridian imwe mugihe numero ya kabiri yerekana imbaraga zikenewe mugukosora indi meridian.Umubare wa gatatu (X 180) uvuga gusa aho meridiya zombi ziryamye (zishobora kuva kuri 0 kugeza 180).
Amaso ameze nk'intoki - nta bibiri bisa neza.Turashaka ko ubona ibyiza byawe, bityo hamwe nubwoko butandukanye bwibikoresho bya lens dushobora gukorera hamwe kugirango tubone igisubizo cyiza kugirango uhuze ibyo ukeneye kugiti cyawe.
Isanzure irashobora gutanga lens nziza kugirango ikosore ibibazo byamaso byavuzwe haruguru.Pls yibanze kubicuruzwa byacu:www.universeoptical.com/ibicuruzwa/
